Created attachment 102867 [details] [review] Possible fix v2.
As noted in the comment the last patch was for 3.15.
Here is an updated patch based on alex drm-fixes-3.16-wip branch.
Tried this on alex drm-fixes-3.16-wip with my R9 270X and it didn't go well.
When doing nothing I am getting errors (attached), later I was transcoding some vids so I guess memory pressure, and then I managed to lock the screen by trying to use uvd. I could SysRq OK - so different for me from before in that respect.
